eas-'PRODUCER To all wwm it may concern:

Be it known that' I, WiLLiA'M B. Citar- MAN, of Brooklyn. city of New Yorlt, county of Kings, State of New York, have invented certain new and useful Improvementsin Gas-Producers, of which the following is a full, clear, and exact s eciiication, such as will enable others skille in the art to which it a pertains to make and use the same.

lily invention relates, to a producer .which may be operated either on the suction or pressure principle for the production of ower or' fuel gases from bituminous coals. he invention resides. in various features of structuijeiand relative arrangement or combination-inf parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

For the purpose of a detailed descri tion,- lllW` reference is had to the accompanyin ingsfwhich illustrate, as examples on two preferable practical embodiments of t e ins vencion, though many and various modificationspf the invention may resorted to withoutlepartingfrom its princi le as expressed1in the claims .all o. whic will be ap arent to persons sinlled in the art.

n said drawin Fi ire 1 is a vertical section ofthe pro ucer; i 2 is a cross .sec. tion thereof on the line 2 of Fi 1; Fig.3 is a'plan view; Fig.- 4 is a detaile section of one of the plows on the line 4 4 of Fig. 1

. a'nd 5 isa vertical section of a secon form o he producer.

Referring first to the structure shown in Figs. 1 to 4; the producer there shown is especially, though not necessarily, designed as of the upright suction type, 10 being the air inlet to the bottom and 11 thes outlet. The producer is illust-rated as wit av metal shell 12, and a tire brick or other refracto linin 14. At the base .of the reducer is an as an 15 above which is t e body of lindrical in form and, in the type shown in Fig. 1, is composed of four superimposed sections 16, 1?',18 and 19. Of these sections, the lowermost, 16, and the upper intermediate,- 18, are ada ted to rotate around a vertical axis,

'while t e remaining sect-ions 17 and 19 are stationary. The lower stationary section 17 is comparatively narrow for a pu ose which will fully appear hereinafter. he

Patented J an. 23, 1912 upper revolving section 18 is flared upward linteriorly to cause the burning fuel to arch 21 which they assist in sustaining. The scction 19 is attached to and sustained by the beams of the lloor 21, and if desired, by Tlie'beains 20 also carry inwardly projecting studs 23 on which are moiiuted rollers 24 which bear under an annular flange 25 on a car ring 26 encirclin and :attached to tie upper rotating section 18. il". mis manner said section is sustained to rotate freely ou the rollers 24. In mesh with the gear ring .26 is a pinion 27 fastened on a vertical shaft E28. rlliis shaft .is mounted at its ends in bearings 29 and has fastened to its lower portion a worm wheel 30 in mesh with a worin 31`mounted and driven in any desired manner. The beams 20 have a second set of studs 32, similar to the studs 23, and carrying rollers 33. These rollers are engaged by and support the hanged lower edge 34 of a gear ring 35 which is firmly joined to the section 16 through a web 36 thus mounting the lower rotating section. 37 indicates a pinion fastened to the shaft 2S und meshed with the gear ring 35 to rotate the section 16. The ratio of the-gearing is such that the sections 16 and 18 turn at different speeds. The studs 32 are adjustably held by bolts 32* fsind he weight of the section 17 is carried by the section 16 as will -fully appear hereinafter and the section 17 is prevented from rotating by a lock chain 22 or other suitable men5- i The edges of the sections of the body of the producer abut each other as closely as is possible in view of the necessary clear` 16. By adjusting the parts 32* and 3Q the itchingof, the vessel in the .case of marine installations and the cost and difficulty ot.y

oonstructin proper seals particularly in producers esigned for tie generation of what islmown as water gas where high pressures are required. To obviate these dif ticultiesI have devised a mechanical seal of two parts with relative sliding motion. To the lower ed of the section 19 is attached an annulus 3 preferably of cast iron with a depending bead 30 running in an annular oove 40 formed in the to of the flange 5. The bead 39 contacts wit i the bottom of the groove 40 and the flange 25 rotating with the section 18 slides under the bead, forinin in this mannera. running or slidinfg joint the surfaces of which are, by the sli ing motion,' round true and therefore made gas tight. I desired, a quantity of graphite may be placed in the groove 40 to liibricate the parts. The lower stationary section li' has attached thereto a double flanged anniilus 42, the u per flange of which is grooved to receive t e bead 4B on an annulus 44 fastened to the lower edge of the upper rotatin section, while the lower flange of the annuus 42 has a bend 45 titing a groove 46 in the web 36 of the gear ring 85. I ii this manner seals similar to that first described are formed between the sections 18. 17 and elevation of the sections` 16 and 17 may be controlled and the parts of the seals kept enaged with the proper pressure. The studs 3 are fitted with similar screws 23 by which similar adjustment of the section 1S may be effected.

s shown in Figs. l and 3, the stationary top of the producer is formed of a number of sections .7 and i7' of cast iron flanged and bolted together and with poke holes 48 therein. These oke holes are normally adapted to be close by plugs 4t) as shown in Figs. 1 and 3. On its under side the sections of the producer top excepting the section 47'* have attached a refractory lining 50, preferably formed in blocks over and between which the top is cast, thus furnishing a convenient means for attaching the liningy In the seetions 47 a circular opening is formed which receives the lower end ot' a charging` hopper 5l. The hop er has a water soa' d cover all at its top an at approxiiiiatcl'v itsi middle is located a gate 53 iiiovalihi lioiizoiitallv on a` bttlii 54 ill till@ liomitfl :Uitl :itliilitwI t() iiil withdrawn to open iaisition into an nii' tight casing o5 projecting troni the vide ot ila', hop im. i

'l ie open bottom of ila licppci communi open atitsfbottlom and-.extends downward- `eccentieally to and in the uppermost section, 19 .of the producer to a point near the lower ed'e thereof. The coking chamber ti is, accor` i'ngto the construction shown 1n Fig. 1, fastened to a dependin flange 47 on the section 47'* of the pro ucer top and formed with s. water chamber 57..4 At its' outer side the coking chamber is let into the 4refractory linin 14 and the lining ring.

. 58 and 60 in icate water inlet and outlet Iipesthrough which water. may becircuated in the chamber 57 to cool the walls of the coking chamber and prevent their destruction y the heat. The lower edge of the coking chamber, as

indicatedglby the dotted lines in Fig. 1.isV

inclined y'spirally and the upper rotating section 18 turned toward the ower ortion of such-edge. The result of this is ti`at the coal 'in fthe producer, rising to the levelindicated in Fig. 1, i. 0. to the lower ed e of the coking chamber, is moved a ainst t ie lower portion of the edge of suci chamber and rolled or dammed up against the same. This elige, therefore, serves to level off the top of the fueland at the same time to etl'ect. a conA stunt rollin agitation thereof, by which a caking or so idiiication of the top of the fuel bed is prevented. The opposite or higher portion of the edge of the coking chamber allows a certain quantity of fiielto he steadily drawn ont of the coking chamber by the rotationof the section 18. In the operation of the producer, therefore, the body of glowing fuel is rotated under the eccentric open bottom cokiiig or feed chamber with the result. that a constant quantity of fuel is uniformly fed from such chamber and -iiniforinly distributed over the fuel bed, while the surface of such bed is constantlyharron-ed or agitated as explained. To till the coal magazine or hopper the Cover 52 should be removed` the gate having first been closed. The hopper iiuiy then he filled above 11o the gate without escape of gas, after which, upon replacing the cover 52,' the gate may be opened to allow the coal to drop into the eokin chamber und a second charge of coal intro uced by again closin the gate andremoving the cove'r. Norma ly, however, the

gate should lic kept. withdrawn into the casinar ."ili to protect the gate from the heat.

When in operation, theyhcat generated in the body of the producer acts on ythe coal 12o l in the coking chamber in such away as to drive off therefrom the more volatileof its gaseous constituents in the 'form of a rich ii-:ivy gas having a high percentage of tar and other bituminous` substances. yAccord- 'ing to my invention this tarry gas is confic. teil around into the body of incandes- -a-:o lool where it is acted on by the incanl dri-cient carbon and transformed into a fixed catcs with a colting ohainoifino which is i giraf. `which may be readily washed and yan ..-ci L iai/Mimosas.

cleansedto prepare it'for use in.l `as engines if desired. Totthis end..I lea( to the narrow section '17of the producer 'and terminates in a duck-bill nozzle 64 which extends' through the walls of, the section'17 Yand discharges intothe (producer. 68 indicates a steam or other flui jet. nozzle discharginginto the' lower end of `the ing `endpf.4 the pipe by which air muv be introduced into thegas therein and which when' open will allow of igniting the mixture thus formed. v By these devices should any of the tarry gas condense in the pipe 6l leaving a tar and soot deposit, thc same may from time to time bc burned out from the pipe, thereb -k'eeping the pipe clear of all suc i accumu ation.

62'* indicates a flame as described.

The operation of the producer causes the body of incandescent coal in the section 18 to rotate past the point of inlet of the gas from the nozzle 64, thereby thoroughlyagitatin the fuel and instantly breaking down or c osing any blow holes, channels or chinineya which might form or start to form by reason of the blast of as from the nozzle 64. Further, the. duckill forni of tho nozzle and the location of the coking chamber above it, tend to diffuse the gas through the entire naiss of coal and prevent it troni passing along a fixed path, which, if such path were followed, would result in forming a blow holt` up through the fuel bed. Since a solid or compact fuel bed is essential to good results. it. follows that the breaking down of blow holes is of the greatest importance.

The lower rotating.: section 16 has an inverted frosto-roniraLskii-t (i5 attinhed to its bottoni odge and irojoi-ting downward into for igniting the\gas 'tbc ash pan l5. 'l his skirt' is provided with horizontal internal ribstii. here shown as two in number, which extend around the skirt and partlyy :support the ash inr'losed by tha suino. Those riba- .wrve also to rcinforrc the skirt. Consequently as the skirt revolves with the producer section 16, this body of ash is carried around with it. Over thc inlet pipo l1) is arranged a tapering nozzie or ash Crusher tii' mounted on the. bottom of the pan l5 and square or lozenge sha )ed in cross section as indicated in Fig. 2. 'llhis ri-usher .nozzle 67 may bcof any angular forni or it might bo round and cccentrically located in the ash pan without materially allocting its operation. The nozzle (i7 is crowned by a pyraiiiidal hood 68 rigidly mounted on the nozzle by brackets 69 and projecting downward over und below the open upper und ot' lu-y nozzle. integral bypass pi e 61 to induce a current therein;` 621m icates an `air valve in the `receiv rwater or otherwise cooled.

By this arrangement I am -ena led to empliy a hood of small'diameter and yet to sprea `out and distribute the draft evenly throughout the entire fuel bed.

The ash is rotated toward the lower edges of the inclined upper surfaces of the plows and the plows t erefore vexert an upward thrust on the ashes above them, the result of which is not only to agitato the ash but to communicate theagiltation in undulatory or wave-like form to t e" fuel bed above the ash. In this manner the fuel bed is la itated by agitating means located in the asi zone and which therefore. do not re uire to'be 95 -Tie lozen c shaped or other angular pyramidal nozz e 67 coacts with the rotating-section 16 and skirt 65'by reason of the rotation of the ash bed around the nozzle, engagin the ash with the angular inclined sides of t ie nozzle and permitting ash to work downward in the gaps or recesses formed behind the ridges of the nozzle and forcing the ound up ash outward toward the edge of t e an. From this point the ash may be easily s ovclcd out of the pan by an attendant.

In the operation o the producer the bot-l tom is first lled with ashes to a level above thc plows and a tire is'kindled on the ashes. 110 The fuel is char d into the producer on t-he tire thus formede andthe fuel'supply continued as the tire spreads until 'the fuel rises to the normal level indicated in Fig. 1. The ash settles in the pan 15 and skirt 115 05 until theoperationassuming its normalcondition, the ais/h and fuel zones take approximately the elevations indicated in Fig. 1. Owing to the ratio of the driving gears the producer sections 16 and 18 rotate at 120 diti'erent speeds, or if desired in opposite directions and as a result the upper part of.

the fuel bed in thesection 18 is twisted with`- respect to the lower part in the stationary section 17 and the diversely rotatin sect-ion 16. This thoroughly agitates an shakes, clown the mass of glowing coal, packing and uniformly distributing it and destroying in/ their -inception any low holes or chim ueys which may tend to form.' The agi-:1w

the fuel is continually fed .to the rodncer aud kept evenlydistributed overt e whole ltest portion of the continua; twistin `It is further to.

surface of the re.'V The rich terry gas given off inthe cokingchainber is drawn there from bv theijet Afrom the nozzle 63 and forced down into thelower part of Ithe fuel bed. From this continuously moving and agitated mass of incandescent fuel diagonally upward to the outlet 11, transformedduring its passage into a permanent gas of such comp sition that it may be. easily washed and cleansed and tittedfor. power purposes. The position of the ash line may be observed through eek holes 71 in the lower-most section" 16. llf'at an timel necessary, the fire maybe hand p ed through the poke holes 48 in thc'pr ucer tops.

. In connection with. the oteration of theI producer, itmay w remarke that the speed of'` rotation of .the sections 16-and 18 is comparatively slow, varying from approximately onel to two revolutions per hour.- l-lence, .very little power is required for this purpose. The rich, tarry ms from the coking--chamber is forced ir -iugh the hotandas thus converted into a clean fixe as, effecting a great avin in heat units w en compared withthe o l Isystem of washing out andv wastin this bituminous element. pointed out that the gas byrpassed into the tire is introduced above the air inletand does not, therefore, combine directly with thei air. This avoids burnin the s and insures that it is properly sidi ectie,l to the nlction of the incandescent: carbon., t

The construction shown in Fig, is of theupdraft rassure principle and differs from the com ruction above described rinci ally ia Ithe form of the seals an ash p ow, the omission of thebyass-from the coking chamber and certain c an es in the construction of auch chamber. In Fig. 5, 72.r,epresents the stationary top section, 73 the upper rotating section, 74 the lower stationary section and 75 the louter rotating or ash section. The three upper sections are brick lined and cyliudric in form and the lower-most section 75 is here lshown as of sheet metal and of .inverted frusta coni cal form. The rotating sections are mount 'the nuoayof theV point it. rises through the.

` BEST AVAlLABLE COPY ed and driven substantially as hereinbefoue 'described Lwith referenceto vFigs` 1 to- 4 except that thesection 74 is sustained b its gate and cover are also unchanged with reference to'Figs.` 1 to 4f.Y The down draft luy-pass from tho coking chamber is omitted from the ,modifiedtype of producer. The coking chamber instead of being 'form'ed of an integral waterchambered .casting is formed of twometal sheets 76and 77, the former. sabstantiall V or V-shaped with its vertical edges astened to the wally of the section 72 and the latter extending across between the. sides of the .former to prevent contact of the coal with the 4brick ining of the roducer and the consequent clinging or ringing up of the coal in the.cokin chamber. The lower edge of the sheet 56 is strenpthened'and protected ,from the heat by a V or V-shaped water 'ipe 78 to which it is attached, while the Ower edg of the sheet 7T is protected by a branch pipe 7 9 extending across between the limbs of the pipe '78.,

The producer sections are Watcrsealed between each other in'FiafA The top scction'72.has a depending skirt 80 at its lower ed which dips'. intofan annular cu 81, bo h arts enciirling the noducer an constituting a seal between tlie sections 72 and 73 maintained 'at all times irrespective of their relative motion. The gear ring 82 of the section 73 carries a shirt 83 and this projects down into an annular cup 84 attached to the upper part of the section 74, producing a similar scalat this point.

romthe lower edge of the section 74 the sheet metal wall 85 projects downward into an annular cup formed by two annular walls 8G and 87 of which the latter is an extension of the section 75 and the former rises from the said section at an acute angle thereto. The gear ring 88 of the section 75 is attached to und eiicircles the wall 87. 88l indicates the ash pan which is adapted to be filled with water and into which the section 75 dips. In the center of the ash pan 88'* and over the air inlet is arranged an air nozzle S9 which Aserves the additional function oan-ami or clinkcr crusher, the same as in Figs. l to 4. 'lhe nozzle 89 tapers upwardly and is of square, lozen -shaped or other angular cross sectiona forni so that the ash bed revolving with the section 75 is carried against the angular sides of the nozzle and the clinkeis ure broken into sniall sections which may lic readily removed with the ash. "`l\c :torni of the nozzle and the rotation ot .he ash also serves to work the ash down and outward in the pan, as hcrcinbefore described. ln the iipper and of the nozzle is a spider 90 supporting a step Ul 0n which bears a stud 92 proiccting down from the under i side of the nozzle hood 93. The u per'siir-A face of this hood is pvramidal in orm'and from the hood ash p ows Dit project. `The hood 93 and plows 94 are similar to-the plows of Figs. 1 to 4 except that the plows extend over to brackets 95 attached t0 the wall 86.0t the lower rotating section, and are ljoined thereto so that the hood and plowsturn with such section. The e'ar rin 8S serves to support the ilows and iood an prevent sagging thereo while the motion of the ploivs and hood and their peculiar formation causes a thorough agitation of the ash settliii the saine and breaking the clinkers. yFuri ier these elements exert an iiiidiilator upstroking action which is coiniiianicatedy through the ash to the fuel bed as before described. It will also appear from Fig. that the nozzle 89 and plows 94 are higher iii the producer than in the other form and thus exert a greater rotating action on the ashes.

The operation of the form of producer shown in Fig. is essentially the .-'aine as that of the producer shown in.- Figs, 1 to l, excepting for the change' in the nature of the draft and the omission of the b -piiss from the coking chamber. The ash p ows in Fig. revolve with tlio lower rotating section and work against the ash in the lower part of tho section 74, this being in a broad sense a incre reversal of the arrangement shown in the other figures. The operation niav be observed from tiinc to time through peel: or test liolcs* in the section 74.
